5. Select Shape to choose the shape of the modulating waveform. Options are: Sine,
Square, Triangle, UpRamp, DnRamp, Noise, Arb.
UpRamp = Upward ramp waveform
DnRamp = Downward ramp waveform
Arb = This will be the waveform that is currently loaded from within the arb function
menu. To change, follow the instructions in the previous section.
6. Select Source and choose between Internal or External.
Internal – The modulating source will be generated internally using the AM
Freq, AM Depth, and Shape as defined in the previous steps.
External – Use external modulating source. Users can connect an external
signal into the rear BNC terminal labeled Modulation In as the modulating
source. AM Freq, AM Depth, and Shape options will not be available.
WARNING: Do not connect more than ± 6 V into the Modulation In terminal. This will
damage the instrument and void its warranty.
DSB-AM
Follow the steps below to setup DSB-AM modulation output.
1. Configure your waveform with the desired frequency and amplitude, then press the
Mod button. Under Type, select DSB-AM.
2. There are three parameters that can be adjusted: DSB Freq, Shape, and Source.
